Binaural Mask-Informed Speech Enhancement for Hearing AIDS with Head Tracking
TL;DR: An end-to-end speech enhancement system for hearing aids which seeks to improve the intelligibility of binaural speech in noise during head movement using a reference beamformer whose look direction is informed by knowledge of the head orientation and the a priori known direction of the desired source.
Journal ArticleDOI
Ray-Space-Based Multichannel Nonnegative Matrix Factorization for Audio Source Separation
TL;DR: In this article, a multichannel nonnegative matrix factorization (MNMF) was proposed to separate multi-microphone convolutive mixtures with Ray-Space-transformed signals, where magnitude data successfully encoded source locations as frequency-independent linear patterns.
DissertationDOI
Study and development of an in situ acoustic absorption measurement method
TL;DR: In this article, a new approach is proposed that takes these effects into account and which is based on the extrapolation of multiple measurements at different loudspeaker heights, in some cases even revealing flaws of the latter.
Journal ArticleDOI
Representation of two-dimensional wave fields by multidimensional signals
TL;DR: This tutorial presents a framework for some of the most common wave-like signal descriptions based on well-known transform domain signal descriptions from multidimensional systems theory.

Evanescentwave reproduction using linear array of loudspeakers
TL;DR: If only the evanescent wave is reproduced, it can be applied for a local area sound reproduction system that can localize a sound field around one specific location.
